Description

Dispensing devices for liquid or creamy ingredients for garnishing food

technical field

The present invention relates to a mechanical dispensing device, particularly suitable for decorating foodstuffs, such as pizza, wafers, cakes, etc., with sauces, creams or generally with liquid or creamy ingredients, the decorations being dispensed by pressure which can be generated by an air pump Use a hose to deliver.

Background technique

Usually, these dispensing devices are installed in a production line or machine, in the upper part of the passage range of the blanks to be decorated, which means that the decoration process is done dripping free. And in order to spread the decorative material evenly on the blank, it is necessary to adopt several hoses or nozzles and air jets, distribute the decorative material on the upper part of the decorative range at reasonable intervals, and distribute the decorative material on the blank.

The known dispensing devices have several disadvantages: systems with multiple hoses and nozzles are particularly unsuitable for toppings like ketchup, because these toppings have different viscosities and properties and are fed from a single supply soft Each nozzle filled with the tube would not be able to spread an equal amount of trim. In addition, spreading through multiple hoses and nozzles can cause hygiene issues, as some will still drip from each nozzle after the trim supply is interrupted. In order to prevent deterioration, mold or bacteria growth of the trim due to molding etc. during downtime, it is necessary to replace nozzles and hoses from time to time, thus increasing the cost.

Systems in which dispersion is provided by air jets require high uniformity of trim used, precise metering, and scaling in terms of texture and volume (amount) of trim, which often leaves over-dispensing or dispensing associated with cleaning problems Insufficient to cause interruption.

U.S. Patent No. 5,921,170 discloses a dispensing device in which the decorative material drips onto the blank below, and the blank is arranged on a base that rotates about a vertical axis and moves in the radial direction, that is to say, it is spread in a helical line. carried out in the form.

This known device is incorporated in a pizza production line, imparting various movements to the blanks, while the nozzles for spreading the topping are stationary.

This method does not use traditional conveyor belts or conveyor chains to transport the blanks. Therefore, transport from the casting point of the blank to the baking position or ejection position is carried out on only one rotating base. And the rotation can take place only in the decoration position, or, from a conventional or at least non-rotating base, mechanically converted to a base suitable for the next processing and/or baking process. This method is too cumbersome, for example, requiring the base to be heated while transporting and/or decorating the blank.

If it is ensured that the helix has a constant slope, the decorative material is spread continuously and evenly, especially at the same speed when touching the blank, then a smooth and regular distribution in the form of a helix is guaranteed.

Even distribution of the trim can also be achieved by adjusting the amount (amount of spread) relative to the rate at which the trim hits the blank.

Contents of the invention

The object of the present invention is to devise a dispensing device as described at the beginning of this text, which can spread the decorative material evenly on the blank, regardless of the nature of the decorative material, and utilize the traditional conveying method or the method that makes the blank in the decoration. It can also be used for processing such as heated transmission, and it helps to maintain good hygiene during cleaning.

In order to achieve this goal, the present invention delivers the trim by equipping it with nozzles and/or hose ends, which have all the necessary movements to distribute the trim evenly over the blank, without special delivery of the blank, which In addition to moving the blank from one process point to the next, this method rotates and/or moves the blank.

Therefore, the present invention makes use of the known system of screw dispensing to drop the decoration onto the blank; in order to achieve this, the invention provides a mechanism rotating around a vertical axis: a screw is mechanically coupled to the rotating part of the mechanism, and radially displacing the nozzle or hose end for dispensing trim while rotating on a horizontal plane above the blank so that the trim is dispensed in a helix with a constant slope without moving the blank. In order to achieve the same spread, the speed at which the spirals are produced is constant throughout the decoration process, preferably starting from the periphery of the blank and ending in the middle. To achieve this goal, the radius of the helix of the mechanism decreases with the increase of the number of revolutions, so the decorative material always falls on the surface of the blank at the same speed.

The device of the present invention comprises a fixed frame with two horizontal discs, a friction ring or ring teeth, installed in the range of the center hole of the lower disc, and on the upper disc, a bushing is installed, pivoted coaxially with said ring and the hole. The device, driven by an electric motor, is fixedly mounted on a bearing plate for a screw; the rotation of the screw moves the bracket axially of the screw and thus the radial movement of the end of the hose supplying the trim. The screw is driven by a friction disc connected to a friction ring, or by a ring tooth that meshes with a ring gear. Rotate the bushing in one direction to turn the bearing of the screw, and through the screw, the support can be moved radially in one direction, for example, outward from the center of the shaft of the bushing, while the friction disc or gear connected to the screw is rotated and mounted on the Friction rings or ring teeth on a retainer. Reverse rotation of the bushing results in movement of the support outward from the region of the bushing's axis of rotation, ie toward the edge region of the lower blank.

A flexible hose for supplying the trim is freely routed through a rotating bushing, which hose is pivoted on a radially movable support so that the trim being dispensed falls naturally onto the blank.

The positioning of the tube ends prevents twisting or kinking of the tube during various movements of the unit and also allows easy removal or replacement of the tube for cleaning and hygiene purposes. The tube preferably comprises a single piece with a tube part of a peristaltic pump for supplying the trim. The invention does not rule out that the speed of the nozzle or the end of the hose used to spread the trim is kept constant, and reducing the radius of the helix will reduce the speed at which the trim is spread onto the blank, which requires a proportional increase in the amount of trim to be evenly accumulated and distributed Trim. In order to limit the cleaning required and maintain hygiene, the device of the present invention allows easy replacement of the hose, which is a single replaceable part with a single pipe connection and thus easily disassembled.

In the following, the dispensing device according to the decoration mechanism of the present invention will be explained in detail using embodiments. Attached is a schematic diagram, which is only for introduction and does not limit the scope of the invention.

Detailed ways

The transverse transport element 1 is secured by clamps 1a to a frame 10 of a conveyor belt or chain 11, and the top of the transport element 1 supports a flat plate 1b with a central hole 1c. A second flat plate 3 coaxial with it and supported by a cantilever 2 is arranged above the central hole 1c. Spaced apart and parallel to the first plate and centrally located, a bushing 4 is provided in the plate 3 so as to be rotatable about the axis via a ball bearing 3a in a direction 3r. On the outer surface of the bushing 4 , a pulley or a groove 4 a for placing a belt 8 is provided for transmitting the movement of the pulley 5 a of the motor 5 to the bushing 4 . Two cantilevers 3e are installed on the bottom surface of the bushing 4, extending downwards, and two parallel bearing discs 6 are installed vertically at the ends of the cantilever for a screw 6c that can rotate in the direction of 6r, a guide rod 6b and a coupling element 6a . One end of the screw 6c cooperates with a friction disc 6e, the end passes through the bearing 6, and the rubber edge 6f on the friction disc 6e rotates the friction ring 1f; the friction ring 1f is installed and fixed in the center of the disc 1b through the rings 1e and 1d edge of hole 1c. In order to ensure that the edge 6f of the friction disc 6e is in firm contact with the fixed friction ring 1f, a ball bearing 6d is provided, fixed on the same bearing disc 6, which is provided with a friction disc 6e, parallel to it and perpendicular to the upper rotating shaft, so that A protruding bearing is formed on the top end of the friction ring 1f.

The bushing 4 that rotates in the direction of 3r, the cantilever 3e and the bearing plate 6 drive the screw rod 6c, and the rods 6a, 6b and the support 9 that is connected with the bearing plate and can rotate in the direction of 9t rotate together. Through the friction disc 6e and the friction ring 1f fixedly connected to the disc 1b, the screw rod 6c is driven to rotate around the axis 3r, and the nut 9b on the bracket engages with the screw rod 6c. A guide portion 9c is provided on the bracket 9, the seat 9g of which slides along the fixed guide rod 6b. When the screw 6c rotates in the direction of 6r, the bracket 9 moves axially along the screw 6c in the direction of 9t, while the guide part 9c smoothly slides along the fixed guide rod 6b to prevent the bracket 9 from twisting. This mechanism makes it possible to link the movement of the support 9 in the direction of 9t with the movement of rotation in the direction of 3r, resulting in the dispensing of the decorative material S in a spiral 13 of constant inclination. In order to ensure that the distribution of the decorative material S on the blank 12 takes place at the same speed and independently of the distance of the end 7a of the hose 7 from the axis of rotation of the bushing 4, and therefore also independently of the distance from the center of the lower blank 12, the number of revolutions of the motor 5 When the support 9 moves from the periphery of the blank 12 to the center in the direction of 9t, it increases as the radius of the helix 13 decreases.

The decorative material S is conveyed axially through the passage 4c of the rotating bushing 4 by means of a flexible hose 7 via pressure generated by, for example, a peristaltic pump. Inside the bushing 4 there is a ball bearing 4b to prevent friction when the hose turns in the direction 3r. The end 7a or nozzle of the hose 7 used to spread the trim S is pivotally connected to a ball bearing 9f mounted on the bracket 9 and is routed by a ring 9e also fixed on the bracket 9 .

The invention does not exclude a screw 6c that extends only slightly longer than the radius of the blank 12 and a gear-driven screw 6c whose movement originates from a gear connected to the fastening mechanism. Furthermore, the invention does not exclude that the device is arranged to be movable so that it is transported with the blank 12 on the conveyor belt 11 without stopping it, and after the decoration process is completed, the device returns to the starting position.

In order to achieve uniform spreading, in addition to the above-mentioned process that provides a variable rotational speed and a constant supply of decorative material S, another process is used: the rotational speed of 3r rotation is constant, and the supply of decorative material S varies with the spiral radius The changes are proportional; in particular, the reduced radius results in an increase in the supply capacity of the pump delivering the device. Furthermore, the invention does not exclude that the bushing 4 is provided on a single disc, which would eventually reach the level of the disc 1b, with friction rings 1f or ring teeth. In this case, the diameter of the axial channel 4c of the bushing 4 is roughly equal to twice the distance of movement of the bracket 9 . The screw 6c can also be arranged in the channel 4c of the bushing 4, or on the upper part of the channel 4c. The bushing 4 can also be replaced by a disc that is arranged on the fixed disc 1b and rotates in the direction of 3r. It has a diameter direction or simply a radial passage, and a screw rod 6c and a support 9 are provided inside or within its range.
